Lab-Grown Diamond Engagement Ring

Imagine the elongated silhouette of a marquise diamond catching the light as it rests gently on your hand, its tapered points drawing the eye with subtle drama. This semi-set engagement ring foundation in warm 18K yellow gold offers a handcrafted embrace designed in our Williamsburg studio, where each curve is shaped and polished to a smooth, comfortable finish.

The low-profile solitaire mounting balances presence with wearability, crafted to sit close to the finger for everyday ease and glove-friendly grace. Its artisan construction reveals meticulous attention to the prong setting, ensuring security while allowing maximum light to animate the stone’s distinctive boat-like form.

Our commitment to ethical jewelry shines through the choice of lab-grown diamonds, offering clarity and brilliance with a significantly reduced environmental footprint. This piece suits those who appreciate a bold yet refined statement, especially flattering on longer fingers or those seeking a ring that elongates the hand.

Should you wish to customize the center stone, our semi-set design invites you to select a marquise diamond up to 12 x 6 mm, tailored to your vision. Resizing is available to ensure a perfect fit, crafted with the same care as the original design.
